Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinning equipment technology, and in particular to a spinning tension regulating device. Background Technology
[0002] A roving frame is a spinning machine that processes fiber slivers into roving. The main functions of a roving frame are drafting and twisting. During the drafting and twisting process, a tension regulating device is usually required to prevent tension fluctuations in the spinning process in order to meet the processing requirements of the roving frame. The stability of the tension directly affects the spinning production efficiency and the quality of the textile products.
[0003] Existing tension adjustment devices are divided into two types: one uses a motor to automatically control and adjust the position of the tension wheel, and the other uses manual control of the tension wheel position. The manual control method has a simple structure and low operating cost. The manually controlled tension adjustment device generally uses a screw drive. The tension wheel is connected to the screw through a connecting part. By turning the screw, the tension wheel is moved vertically to complete the tension adjustment.
[0004] Existing manually controlled tension adjustment devices use a single screw drive, offering only one adjustment method and failing to meet the needs of both coarse and fine adjustments. The tension wheel position adjustment accuracy is low, easily leading to over-adjustment, which can significantly impact spinning continuity and product quality. Furthermore, existing manually controlled tension adjustment devices typically only adjust the position of the tension wheel, while the guide wheels on both sides remain fixed. This makes it difficult to flexibly adapt the wrap angle and contact state of the yarn between the guide wheels and the tension wheel, easily resulting in uneven tension across different parts of the yarn. This affects the uniformity of yarn twist, reduces yarn quality, and increases the breakage rate during subsequent weaving processes. Utility Model Content
[0005] To address the technical problems of existing manually controlled tension adjustment devices in the background art, which employ single-screw drive, have low tension wheel position adjustment accuracy, are prone to over-adjustment, and easily affect the continuity of spinning and product quality, this utility model provides a spinning tension adjustment device.
[0006] The technical solution of this utility model is as follows:
[0007] This utility model provides a spinning tension adjustment device, comprising: a tension wheel and a guide mechanism rotatably disposed within a housing, the guide mechanism being disposed on both sides of the tension wheel; a threaded rod is threadedly connected to the tension wheel via a first connecting component, the threaded rod being vertically positioned, and an adjusting sleeve is threadedly connected to the threaded rod via a second connecting component, the threaded rod being inserted into the adjusting sleeve and extending upwards, the top ends of both the threaded rod and the adjusting sleeve extending out of the housing, both the threaded rod and the adjusting sleeve having external threads, and the thread pitches of the threaded rod and the adjusting sleeve being different, by setting threaded rods and adjusting sleeves with different thread pitches, different amplitudes of adjustment of the tension wheel position can be achieved when the threaded rod and the adjusting sleeve are rotated respectively, larger thread pitch adjustment can achieve rapid coarse adjustment, and smaller thread pitch adjustment can perform fine fine adjustment, improving the flexibility and accuracy of tension adjustment, meeting the diverse needs of different spinning processes for yarn tension, and the threaded rod being inserted into the adjusting sleeve improving the compactness of the structure.
[0008] Preferably, the first connecting assembly includes a first mounting box rotatably connected to the threaded rod. The threaded rod vertically passes through the top of the first mounting box and is inserted into the adjusting sleeve. A first connecting block is slidably disposed inside the first mounting box. The first connecting block is threadedly connected to the threaded rod. A first sliding rod is fixedly connected to the bottom end of the first connecting block. The first sliding rod passes through the bottom end of the first mounting box. A mounting seat is fixedly connected to the bottom end of the first sliding rod. The tension wheel is rotatably disposed on the mounting seat. The first mounting box provides a stable installation and movement space for the threaded rod and the first connecting block. The threaded connection between the first connecting block and the threaded rod allows the rotational motion of the threaded rod to be converted into the vertical linear motion of the first connecting block, thereby driving the first sliding rod, the mounting seat, and the tension wheel to move up and down, thereby adjusting the position of the tension wheel. At the same time, the cooperation between the first sliding rod and the first mounting box ensures the stability of the tension wheel during its vertical movement, preventing it from shaking or shifting, and ensuring the accuracy of yarn tension adjustment.
[0009] Preferably, the second connecting assembly includes a second mounting box fixedly mounted on the housing, an adjusting sleeve rotatably mounted inside the second mounting box, the adjusting sleeve vertically penetrating the top of the second mounting box, a second connecting block fixedly connected to the top of the first mounting box via a second sliding rod, the second connecting block slidably mounted inside the second mounting box, and the second connecting block threadedly connected to the adjusting sleeve. The second mounting box restricts the position of the adjusting sleeve, enabling it to rotate stably. The second connecting block is threadedly connected to the adjusting sleeve and connected to the first mounting box via the second sliding rod, allowing the rotation of the adjusting sleeve to drive the second connecting block to move up and down. This, in turn, drives the first mounting box, the first connecting block, and the tension wheel to move synchronously via the second sliding rod, further enhancing the stability and continuity of the adjustment. This ensures that the tension wheel remains in the correct position and direction during the adjustment process, improving the reliability of tension adjustment. Furthermore, the use of the first connecting assembly enables segmented adjustment, improving the flexibility and accuracy of tension adjustment.
[0010] Preferably, the threaded rod and the adjusting sleeve have the same thread direction. The same thread direction makes it more convenient and faster for the operator to adjust. The operation direction is consistent, which makes it easier for workers to quickly master the adjustment method and reduce operation errors. At the same time, when adjusting the threaded rod and the adjusting sleeve at the same time, since the thread direction is the same, the adjustment actions of the two are coordinated and there will be no conflict in the adjustment direction, which helps to improve the adjustment efficiency.
[0011] Preferably, the pitch of the threaded rod is less than the pitch of the adjusting sleeve; or, the pitch of the threaded rod is greater than the pitch of the adjusting sleeve. When the pitch of the threaded rod is less than the pitch of the adjusting sleeve, rotating the threaded rod allows for fine adjustment, suitable for making small adjustments to the yarn tension to meet high-precision spinning requirements; while rotating the adjusting sleeve allows for larger-amplitude adjustments, used to quickly change the position of the tension wheel to adapt to different tension adjustment needs; conversely, when the pitch of the threaded rod is greater than the pitch of the adjusting sleeve, the function is the opposite, providing operators with multiple adjustment methods that can be flexibly selected according to actual conditions, further improving the applicability of the device.
[0012] Preferably, a handwheel is fixedly installed at the top of the threaded rod and the adjusting sleeve respectively. The two handwheels are arranged vertically and do not interfere with each other. The arrangement of the handwheels makes it convenient for the operator to rotate the threaded rod and the adjusting sleeve. By manually rotating the handwheels, the rotation angle of the threaded rod and the adjusting sleeve can be controlled more easily and accurately. The vertical arrangement of the handwheels and their non-interference allows the operator to easily operate the two handwheels separately and make adjustments individually or simultaneously as needed, improving the convenience and flexibility of operation.
[0013] Preferably, the guiding mechanism includes an eccentric shaft detachably mounted on the housing, a shrinking sleeve fitted on the eccentric shaft, and a nut threaded onto the eccentric shaft. The nut is used to press the shrinking sleeve to deform and fix the eccentric shaft. A guide wheel is rotatably connected to the eccentric shaft. The position of the guide wheel can be finely adjusted by rotating the eccentric shaft, allowing for flexible adjustment of the angle and position of the guide wheel according to the actual running conditions and tension requirements of the yarn. This ensures a more reasonable wrap angle and tension distribution of the yarn on the guide wheel, effectively reducing yarn wear and uneven tension. The cooperation between the shrinking sleeve and the nut facilitates the fixing and adjustment of the eccentric shaft, ensuring the stability of the guide wheel during operation. The detachable installation method facilitates the maintenance, replacement, and adjustment of the guiding mechanism, improving the maintainability of the device.
[0014] Preferably, the box body has a yarn inlet and a yarn outlet on both sides, and a tension sensor is fixedly installed inside the box body. The tension sensor is located directly above the yarn outlet. The tension sensor can monitor the tension of the yarn at the yarn outlet in real time. Based on the feedback from the tension sensor, the operator can adjust the threaded rod and the adjusting sleeve in a timely manner to precisely control the yarn tension, thereby ensuring that the yarn is always in a suitable tension state throughout the spinning process, improving yarn quality and production efficiency.
[0015] As can be seen from the above technical solutions, the advantages of this utility model are:
[0016] 1. The tension wheel is threadedly connected to a threaded rod via a first connecting assembly. The threaded rod is threadedly connected to an adjusting sleeve via a second connecting assembly. The threaded rod and the adjusting sleeve have different pitches. By setting threaded rods and adjusting sleeves with different pitches, the position of the tension wheel can be adjusted to different degrees when the threaded rod and the adjusting sleeve are rotated respectively. Larger pitch adjustment can achieve rapid coarse adjustment, while smaller pitch adjustment can perform fine fine adjustment, improving the flexibility and accuracy of tension adjustment and meeting the diverse needs of different spinning processes for yarn tension. The threaded rod is inserted into the adjusting sleeve, which improves the compactness of the structure.
[0017] 2. The threaded rod and the adjusting sleeve have the same thread direction. The same thread direction makes it more convenient and faster for the operator to adjust. The operation direction is consistent, which makes it easier for workers to quickly master the adjustment method and reduce operation errors. At the same time, when adjusting the threaded rod and the adjusting sleeve at the same time, since the thread direction is the same, the adjustment actions of the two are coordinated and there will be no conflict in the adjustment direction, which helps to improve the adjustment efficiency.
[0018] 3. The guide wheel is installed in the housing via an eccentric shaft. The eccentric shaft allows the position of the guide wheel to be finely adjusted by rotating the eccentric shaft. The angle and position of the guide wheel can be flexibly adjusted according to the actual running conditions and tension requirements of the yarn, ensuring a more reasonable wrap angle and tension distribution of the yarn on the guide wheel, and effectively reducing yarn wear and uneven tension.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0026] In a typical embodiment of this utility model, such as Figure 1 As shown, a spinning tension regulating device is proposed, including: a housing 1, a yarn inlet 2, a guiding mechanism 3, a tension wheel 4, a tension sensor 17, and a yarn outlet 18. The yarn inlet 2 and the yarn outlet 18 are arranged opposite to each other on the housing 1 for the yarn to enter and exit the housing 1. The guiding mechanism 3 and the tension wheel 4 are both rotatably arranged inside the housing 1. There are two guiding mechanisms 3, which are distributed opposite to each other on both sides of the tension wheel 4. They not only guide the spinning process but also work with the tension wheel 4 to regulate the spinning tension. The tension sensor 17 is fixedly arranged on the inner wall of the housing 1 and is located directly above the yarn outlet 18. After the yarn enters the housing 1 from the yarn inlet 2, it passes through the guiding mechanism 3, the tension wheel 4, the guiding mechanism 3, and the tension sensor 17 in sequence, and then exits the housing 1 through the yarn outlet 18. The tension sensor 17 can monitor the tension of the spinning process online.
[0027] Understandably, the tension sensor 17 is also connected to the monitoring system to transmit monitoring data to the monitoring system, facilitating online monitoring of yarn tension by staff.
[0028] like Figure 1 As shown, the tension wheel 4 is installed inside the housing 1 through a multi-stage adjustment mechanism. The multi-stage adjustment mechanism includes a threaded rod 6, an adjusting sleeve 7, a first connecting assembly 8, and a second connecting assembly 9. The threaded rod 6 and the adjusting sleeve 7 are coaxially arranged, and both the threaded rod 6 and the adjusting sleeve 7 are provided with external threads. The adjusting sleeve 7 is a hollow structure and is vertically rotatably mounted on the housing 1. The top end of the adjusting sleeve 7 penetrates the housing 1 and extends outward. The upper part of the threaded rod 6 is inserted into the adjusting sleeve 7, and the top end of the threaded rod 6 extends outward from the adjusting sleeve 7. The lower part of the threaded rod 6 extends downward from the adjusting sleeve 7. The threaded rod 6 and the adjusting sleeve 7 can rotate relative to each other. The pitch of the threaded rod 6 is different from that of the adjusting sleeve 7. The tension wheel 4 is threadedly connected to the threaded rod 6 through the first connecting assembly 8. The threaded rod 6 is also threadedly connected to the external thread of the adjusting sleeve 7 through the second connecting assembly 9. Under the action of the threaded rod 6 and the adjusting sleeve 7, the vertical position of the tension wheel 4 can be adjusted in segments to meet different adjustment requirements.
[0029] Specifically, when the adjusting sleeve 7 is rotated, the threaded rod 6, the first connecting component 8, and the tension wheel 4 can be moved vertically as a whole under the drive of the second connecting component 9; when the threaded rod 6 is rotated, the tension wheel 4 can be moved vertically through the first connecting component 8. Since the thread pitch of the threaded rod 6 and the adjusting sleeve 7 are different, the position of the tension wheel 4 can be coarsely and finely adjusted.
[0030] like Figure 2 As shown, the first connecting assembly 8 includes a first sliding rod 10, a first connecting block 11, and a first mounting box 12. The first mounting box 12 is rotatably connected to the threaded rod 6. The upper part of the threaded rod 6 vertically passes through the top of the first mounting box 12 and is inserted into the adjusting sleeve 7. The threaded rod 6 is rotatably connected to the first mounting box 12 through a bearing. The first connecting block 11 is slidably disposed in the first mounting box 12, and the first connecting block 11 is threadedly connected to the rod body of the threaded rod 6 in the first mounting box 12. Thus, when the threaded rod 6 is rotated, the first connecting block 11 can be driven to move vertically. The bottom end of the first connecting block 11 is fixedly connected to the first sliding rod 10, and is fixedly connected to the tension wheel 4 through the first sliding rod 10. When the first connecting block 11 moves vertically, the tension wheel 4 can be driven to move vertically through the first sliding rod 10.
[0031] In this embodiment, there are two first slide rods 10. The two first slide rods 10 extend vertically through the bottom end of the first mounting box 12. The bottom ends of the two first slide rods 10 are fixedly connected to the mounting base 5. The tension wheel 4 is rotatably mounted on the mounting base 5. The first slide rods 10 serve to guide and restrict the rotation of the first connecting block 11 around the axis, thereby ensuring the adjustment of the position of the tension wheel 4.
[0032] It is understood that in other embodiments, a guide groove may be provided on the inner wall of the first mounting box 12, and the two ends of the first connecting block 11 may be engaged with the guide groove of the first mounting box 12 to guide the first connecting block 11 and ensure the vertical movement of the first connecting block 11.
[0033] The second connecting assembly 9 includes a second sliding rod 13, a second connecting block 14, and a second mounting box 15. The second mounting box 15 is fixedly installed on the housing 1 by welding, bolting, or other methods. The adjusting sleeve 7 is rotatably connected to the second mounting box 15 via a bearing. The upper part of the adjusting sleeve 7 extends outward from the housing 1 through the second mounting box 15, and the lower part of the adjusting sleeve 7 is placed inside the second mounting box 15. The top of the first mounting box 12 is fixedly connected to the second sliding rod 13. The second sliding rod 13 vertically passes through the bottom of the second mounting box 15 and extends into the second mounting box 15. The top of the second sliding rod 13 is fixedly connected to the second connecting block 14. The second connecting block 14 is slidably disposed within the second mounting box 15, and the second connecting block 14 is threadedly connected to the external thread of the adjusting sleeve 7. Thus, when the adjusting sleeve 7 is rotated, the second connecting block 14 can be driven to move vertically. In turn, the second connecting block 14 and the second sliding rod 13 drive the first mounting box 12, the threaded rod 6, the first connecting block 11, the mounting seat 5, and the tension wheel 4 to move vertically as a whole, so as to realize the segmented adjustment of the position of the tension wheel 4. In order to improve the stability of the adjustment, a guide groove can also be provided in the second mounting box 12, and the two ends of the second connecting block 14 can be slidably connected to the guide groove in the second mounting box 12.
[0034] It is understandable that the second slider 13 can be set to one or multiple, and the specific number can be selected according to actual needs. There are no further restrictions here.
[0035] The thread direction of the external thread of the threaded rod 6 is the same as that of the external thread of the adjusting sleeve 7. In this embodiment, the pitch of the threaded rod 6 is less than the pitch of the adjusting sleeve 7. Specifically, the pitch of the external thread of the threaded rod 6 is 1 mm, and the pitch of the external thread of the adjusting sleeve 7 is 8 mm. In other embodiments, the pitch of the threaded rod 6 can also be set to be greater than the pitch of the adjusting sleeve 7. Specifically, the pitch of the external thread of the threaded rod 6 is 8 mm, and the pitch of the external thread of the adjusting sleeve 7 is 1 mm. Thus, by rotating the threaded rod 6 and the adjusting sleeve 7 respectively, the tension wheel 4 can be adjusted in segments to meet the fine or coarse adjustment of the position of the tension wheel 4, thereby achieving fine or coarse adjustment of the yarn tension.
[0036] To facilitate the rotation of the threaded rod 6 and the adjusting sleeve 7, a handwheel 16 is fixedly installed at the top of the threaded rod 6 and the adjusting sleeve 7 respectively. The two handwheels 16 are arranged one above the other and do not interfere with each other, so as to facilitate manual turning of the threaded rod 6 and the adjusting sleeve 7.
[0037] The guide mechanism 3 is installed inside the housing 1 for guiding the yarn and adjusting the auxiliary tension, such as... Figure 3 As shown, the guide mechanism 3 includes a guide wheel 19, an eccentric shaft 20, a shrink sleeve 21, and a nut 22. The guide wheel 19 is rotatably mounted on the eccentric shaft 20 via a bearing. The eccentric shaft 20 is horizontally inserted into a mounting hole on the side wall of the housing 1, and a shrink sleeve 21 is fitted around the outside of the eccentric shaft 20. The eccentric shaft 20 is threadedly connected to the nut 22. The shrink sleeve 21 is located between the housing 1 and the eccentric shaft 20. The shrink sleeve 21 can be compressed and deformed by the nut 22, thereby eliminating the gap between the eccentric shaft 20 and the mounting hole, so as to achieve the fixed installation of the eccentric shaft 20.
[0038] In practical use, the position of the guide wheel 19 can be adjusted by rotating the eccentric shaft 20 around the axis to change the axial position of the two guide wheels 19, thereby adjusting the wrap angle of the yarn on the guide wheel 19 so that the tension of each part of the yarn is balanced.
[0039] The specific working principle is as follows (taking the example of the thread pitch of the threaded rod 6 being less than that of the adjusting sleeve 7):
[0040] After the yarn enters the housing 1 through the yarn inlet 12, it first passes around as shown in the image. Figure 1 The yarn passes above the left guide wheel 19, then around the underside of the tension wheel 4, then around the top of the right guide wheel 19, and finally around the top of the tension sensor 17 before exiting through the yarn outlet 18.
[0041] When tension adjustment is required, the adjusting sleeve 7 can be turned, and under the drive of the second connecting block 14, the second slide rod 13, the first mounting box 12, the threaded rod 6, the first connecting block 11, the mounting seat 5, and the tension wheel 4 move vertically as a whole to perform coarse adjustment of the position of the tension wheel 4, thereby achieving coarse adjustment of the yarn tension; then the threaded rod 6 can be turned, and under the drive of the first connecting block 11, the tension wheel 4 can be moved vertically through the first slide rod 10 to complete the fine adjustment of the position of the tension wheel 4, thereby achieving segmented tension adjustment to meet different adjustment needs and ensure the continuity of spinning and product quality.
[0042] When the tension of different parts of the yarn is uneven, in addition to adjusting the position of the tension wheel 4, the nut 22 can be removed and the corresponding eccentric shaft 20 can be rotated to adjust the axis position of the guide wheel 19. After the adjustment is completed, the nut 22 is reinstalled to tighten the expansion sleeve 21, thereby fixing the position of the eccentric shaft 20. This changes the axis position of the two guide wheels 19, thereby adjusting the wrap angle of the yarn on the guide wheel 19, so that the tension of different parts of the yarn is balanced and the product quality is improved.
[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
